Doorbell stops gaining power from the fully charged battery

Hello, recently the ring doorbell has gone offline but when I check the battery is fully charged. Seems like the battery to doorbell is becoming disconnected after 5 or 10 mins being put back up. Any ideas?

Or the battery, which is showing 99% power after a recharge, is faulty???

Hi @user62633. What is the RSSI for this doorbell? This is found in the Ring app in the Device Health menu.
